Installation Manual
☐ Conductor cross-section: 0.2mm² to 2.5mm² (24 AWG to 14AWG)
☐ The conductor type and wiring method must be appropriate for the application and location.
Procedure:
1. Remove the sealing plug from the opening for connecting the switch for secure power supply
operation.
2. Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
